The home page in this series on building raised bed gardens is Raised Beds Jim’s Way.
- 10 ga self-tapping wood screws between 3″ and 4″ in length.
- We need 16 for each bed.
- Different diameter screws are OK, but the fender washers must match, so the head of the screw doesn’t pull itself through the washer when being attached.


- Fender washers (pictures above)
- The holes must be large enough for the long screws, above.
- The holes should not be too big for the screw; the head should not be able to pass through the hole, even when using a power tool to drive the screw.
- The outside diameter must be at 1″ and 1-1/2″.
- #12 wood or sheet metal screws between 1″ and 1-1/2″ in length
- Need 32 for the corners of each bed, PLUS
- Need 4 more for each 4′ of bed length beyond the first 4′. So, a 12′ bed needs two sets on each side.

- 1-1/2″ PVC 40 pipe (hard plastic, white)
- These will be cut into equal segments about 6″ longer than the height of the planks.
- The pipe comes in 10′ lengths.
- We need 4 segments for each 4′ of bed length, plus 4 more for one end of the bed.
- Plumbers’ strapping
- These are cut into 9″ and 10″ inch segments.
- We need four 10″ segments for each 4′ of bed length.
- We need four more 10″ segments for one of the ends of the bed. (The other end is counted in the previous statement above.)
- We need eight 9″ segments for the corners of bed (two per corner).
